Urouonxnnm'raxnn'mrnn To all lwhom t may concern Be it known that I, HENRY R. IH o1\(rsoN, a citizen ofthe United States,"res1d1ng at Falls Church, in the county of Fairfax. and

State of Virginia, have invented certain new and useful Improvements in Automobile Intake Heaters, of which` the following' isa specification.

This invention relates to certain Ynew vand useful .improvements in automobile' intake heaters and the primary .object thereof is to provide an inta e heater of the electrical type which heatsthe mixture for startingand is then cut out to allow the exhaust.

gases' to continue the heating of the mixture, combined with manual control means, which upon being given a redetermined movement, eflectsenergization of thefheater and at the same time cuts off the communication between the exhaust manifold and the heater to-prevent cold air enteringthe intake; and which control means after starting and. consequent heating of the exhaust manifold and upon-being given a second movement, cuts out the electrical heater and establishes communication between the heated Veillialist ases of the exhaust' manifold and .the eater. c

The invention furtl1er" 'l rovide' control means which can be insta e on the dash board of the automobile andzalso va 4structure which can be easily` tappedinto connection -with the exhaust mani old.

. Still further the invention .aimsto provide a heater structure which will enable the use 'of keros e as a motive fluid or jcombustible mixtur v l The invention also v aimstev provide 'a' heater and control structure which-can be` easily and quickly ap lied t9 automobiles as istinguished from aI vention, partly broken away and'in section. l In proceeding 'in accordance .with thepresent invention, a heater is employed which consists of a body 1 having end. caps starting however',"lL-Hf@vv exhaust manifol onto the intake manifold 4. Thel heater has rxoirrson, or ranns'cnuncrf, v InGINIa; Ass'IeNon or omi-rum' To may r. Lowa, or WASHINGTON,l Drs'ralc'r or COLUMBIA.

.a pair 'of spaced foraminous plates .5 therein arranged on opposite sides of 4a perfo`- rated pipe 6 'that extends into the body'1.l

'Ihe leg of a hollow -T-shaped member is connected to a pi 7 that is tapped vintothe exhaust mani old 9 while a preferably flexible pipe 10 is connected to the pipe and to oneend of the horizontalpart of the T-shaped memberl 8. One of the platesl 5 has a central hole 11 which-.receives a ter' minal member 12 that-is suitably bolted to .the plate, the terminal member 12- being connected b v a cable 13 to the starter 14. Asecond ca le 15 leads from the starter'14 and connects 'to atermin'al 16 suitably connected to the dash 17 A second and similar terminal 18 is connected to the dash and is connected to a .cable 19 which latter leads to the battery. The terminals 16 and .18 have s ring'ingers 20 and 21 secured at onel en thereto, thei olppositey ends of the fingers beingv free an lunger 22. A metal conductor 23 gagement with the fingers in one osition of the plunger. Thefront endof-t ejpllu'nger extends outwardlyI from the front of the dash and is shaped to afford .a hand ip for ready engagement by the fin rs cfg-the aving Africtional engagement with a -combined circuit and'exhaust manifold controlling (p viscarrie by the plunger'and has direct enA operator, while the rear end of t e lun r is shaped to afford a valve 24:,whic sli es within the o posite end of the horizontal part of the -member 8` and controls communication between' pi` l7 and 10'. If desired a spring 25 may used to tension the plunger so as to normally urge the latter outwardly in which outward position anonconductor 26 carriedv by the plunger 22 engages the spring 'lin rs 20gand 21.

n operation, wit the position depicted in the drawings, it will be seenthat the communication between the exhtaam'anifom (throughv ipe 7) and the' beaten open,. consequent y the .hot exhaust gases will freel enter pi e 6 and then the heater and will? 'eat the atter. U n

cold and it is consequently desirable that 4the cold air therein be cut off from the heater, and to accomplish this` and also at rthesame time to energize the heater and the parts occupying which causes the valve 24 to close communication between the heater and theexhaust manifold Aby covering the end vof pipe 7 where the latter enters T-member 8, 4and at the same time causes the metal conductor 23 to engage the fingers 20 and 21,. thereby tion illustrated'in the drawings, which cuts outthe heater and causes the latter toV be heated by the -hot exhaust gases. The leg 7 supports the member 8, while the plunger is supported by the dash affording an economical assemblage of the parts.

It has also been demonstrated that by introducing some of the hot exhaust gases from the exhaust manifold into the heater between the foraminous plates thereof and through the interposed perforated ipe, that kerosene can be used as a motive uid, the hot gases being broken up by the plates and pipe, while the kerosene is similarly broken up by the plates and pipe in passing from the carburetter through the heater |to the intake manifold, the hot exhaust gases and the kerosene uniting to form a combustible mixture.

What is claimed is:

1. In combination with the exhaust and intake manifolds and the carbureter of an automobile, a -heater connected to the carbureter and intake manifold and having electrical heating means therein, a T-member having its leg connected to the exhaust manifold, means to connect one end of -the leg to the heater, a pair of terminals which with the heater and the electrical heating means are in the electric circuit of the automobile, a spring finger connected to each terminal, and a zontal part oft e =["-member and having a conductor to engage each spring finger and thereby close the circuit through the heater in one position of the plunger and having a non-conductor which 1n a second position of the plunger maintains the circuit through theheater open, and a valve on the plunger to close the communication between the exhaust manifold and the heater when the .plunger is in said first named position and to open such connection when the plunger is in the second named position thereof.

2.
